14 Claims.

This invention relates to a speed feed manifolding attachment for typingmachines having a platen mounted upon a carriage for translation past afixed typing location.

It is a purpose of the invention to provide an attachment that may beadapted for-use with tively feeding superposed; webs or sheets of-paper,

interleaved with sheets of carbon paper into typing relation with theplaten and to automatically retract the carbon paper sheets as a unit toa position to begin a new typing operation, while maintained ininterleaved positions between said webs.

A further object is to provide means positively holding the superposedwebs in proper relation and moving with them during line spacingmovements, but manually releasable from the webs and movableindependently to a position engaging the webs for the next succeedingtyping operation.

A still further object is to provide a frame construction in anattachment of the character described and using a plurality of endlesschains or other band elements, wherein the effective lengths of thechains may be quickly and easily varied and the chains given the propertension.

Another object is to provide a novel connection between the chains orother elements, as in the preceding paragraph, and the carbon paperattaching mechanism, whereby all parts connected to the chains may bequickly adjusted into proper relation.

Another object is to provide a universal speed feed manifoldingattachment that is relatively simple and inexpensive to construct,easily operated, efiicient, rapid and positive in operation and that maybe held in position simply by resting the weight of the typing machinethereon.

Another object is to provide a universal speed feed manifoldingattachment that can be rendered inoperative without removing the typingmachine therefrom or removing the manifolding machine from the typingmachine.

Other objects and advantages of our invention will become apparent asthe description proceeds.

Referring now in detail to the drawing wherein like reference charactersidentify corresponding parts throughout, M, Figure 2, indicates theframe of a machine of standard construction with which our invention isadapted for use and which may be a typewriter, billing machine, or othermachine 0, having a platen P rotatable on its axis to effect linespacing and sweep feeding of the paper, and movable axially to effectletter and word spacing. At F we have indicated a fan-folded stack ofpaper forms folded along hinge sections and threaded through theattachment and around platen P. While the paper supply has been shown asa folded stack, it will be understood that the invention is not limitedto a supply in this particular form, but, if desired, may be in the formof a roll.

A base is formed of sheet metal and has lts rear and side edges Illa and[0b upturned and overlapping at the corners, as indicated at Inc, Figure3. A bolt Hid passes through aligned holes in the overlapping edges tounite them into a reinforcing rim. This base is adapted -to be securedin any desired manner to the typing machine with which it is used. Theconnection may be effected simply by resting the rear portion of themachine on base 18, Or it may be made positive as by means of bolts orlatches, not shown. A pair of sockets II are attached to base [0. Ahollow column i2 is secured at its lower end within each socket II, asby means of a set screw I3. The upper ends of the columns l2 are axiallysplit as at lZa, Figures 2 and 3, to form resilient portions eachencircled by a clamp 14 having apertured lugs 14a. Each column 12 isbraced at its upper end by a sloping bracket [6 which may consist of ametal strap secured at one end to base ID by means such as a screw ll.At its upper end, each bracket is secured to the lugs of its clamp I4 bya screw 15 which passes through aligned apertures in the bracket andlugs. A post [8 slidably fits within each column i2 and is secured invertically adjusted position therein by constriction of the upper splitsections of column 12 when screws l are turned home to draw lugs [40.together. Screws I5 therefore, perform the dual function of clampingposts l8 in adjusted height and securing brackets IE to the upper endsof columns I2, to hold the parts rigidly in position.

The posts l8 are rigidlyconnected together in parallel relation, bytracks 19. These members l8 and 19 are secured together as by rivets 28to conjointly form a track frame 2| wherein tracks 19 are parallel andsubstantially coextensive with the width of the machine. By looseningscrews I5 the frame 2| may be adjusted in height for the particularmachine with which the invention is to be used, after which the saidscrews are tightened to rigidly hold said frame in the desired positionof vertical adjustment.

.A carriage, indicated generally by numeral 22, Figures 1 and 2, isformed by bars 23 secured in spaced parallel relation by short strips ofangle bar 24. A series of rollers 25 are journaled on anti-frictionbearings at spaced points along bars 23. These rollers have theirperipheries grooved and are so spaced in a vertical direction as toengage the facing edges of tracks l9 whereby carriage 22 is freelymovable along said tracks by and with the axial, type and letter spacingmovement of platen P, through connections subsequently described.

Reverse angle brackets 26 are fixed at one end by rivets or bolts 28, tothe angle bars 29, as shown in Figure 2, and have their offset endspivotally connected, as at 21, to the bars 24. The brackets 26 have thedepending end portions 26a which abut the pins 24a when the unit is inits Figure 2 position. As shown in Figure 4, bars 29 are interconnectedat. their upper ends by a spacer rod 3! that also has a reduced threadedhole.

portion 3la passing through alined holes 32 in the adjacent bar 29 and aclamp bracket 30. A nut threaded on said reduced end, acts to secureeach bracket 30 in position on its bar 29. It will be understood thatthe construction shown at Figure 4 is duplicated at the other end of rod3! whereby the two bars 29 are held in spaced relation at their upperends.

Each bracket 30 is bent as at 38a, to encircle the upper end of a tube33. The portion of each tube encircled by clamp 30 is longitudinallysplit, as at 33a, Figure 4, whereby, when the nut on bolt 34 istightened, the tube is constricted into binding contact with a rod 35otherwise axially slidable within and along its tube. An offset bracket33 is fixed to each rod 35 to extend a short distance rearwardlytherefrom. At their free ends, these brackets rotatably support a shaft31 having fixed thereon a roller 44 over which the paper supply passes,as will be described later.

A guide plate 38 has its ends secured tangentially to the respectivecircular portions of brackets 30, as by means of screws 39, to thusextend transversely across the upper front portion of the attachment.Plate 38 is slotted as indicated at 38a. and 38b, Figure 1, and a pin 48is fixed in adjusted position ineach slot, as by means of washers 41,and 42, and screw 43, as will be obvious from inspection of Figure 4.Pins 48 are intended to be so adjusted as to contact the edges of thepaper and guide it downwardly after passing over roller 44. By thisconstruction, on loosening of bolts 34, rods 35 may be telescopedwithin, or withdrawn from tubes 33, to vary the elevation of roller 44,for a purpose subsequently described.

From Figures 2 and 5, it will be noted that each tube 33 is slottedlongitudinally along substantially one-half of its lower length. Thisslot has an angular extent in cross section less than so that sectionsof rod 45 positioned within the tubes, are limited to sliding movementtherealong. Each section '45 has a flattened side, as indicated in Fig.5, into which opens a tapped The flattened side lies substantially belowthe edges of the tube slot so that an element as 46, may be adjustablyfixed along the slotted portion of the tube by tightening a screw 47passing through the element and engaging r the tapped hole in section 45to thereby bind the section 45 within the tube.

In Figure 5, the foregoing construction is used to mount a pair of arms45 for adjustment on and along the respective tubes 33. The arms areapertured at their rearward ends and jointly journal a shaft 48 havingidler sprockets 49 affixed thereto, so that, by loosening screws 4's",arms 43 may be adjusted along tubes. 33 to vary the tension in chains 50and GI passing thereover and subsequently described in detail. Othersections 45 are used to adjustably mount a guide I85, Figure 2, and apair of brackets 5! described in detail later. Each arm 46 at its freeend, extends into sliding contact with. one leg of angle 29, and, midwayof its ends, rotatably supports one end of a shaft 48 having fixedthereon a pair of spaced sprockets 43 and 50. It will be noted that rods3.5 and .45 are separate and distinct elements. Also, as will be notedfrom Figure 2, each bar 23 and its associated tube 33 make a small acuteangle with each other.

A bracket 5.! connects the lower end of each bar 23 with thecorresponding end of its associated tube 33. One end of this bracket issecured to tube 33 and rod 45 in the manner explained tioned as togreases g in connection with arm 46, while the other; or free end,rotatably supports one end of a shaft 52, both ends being similarlymounted. A pair of sprockets 53 are fixed to shaft 52.

Each tube 33 has a bracket 54 secured to its lower end, and thesebrackets rotatably support between them, a shaft 55 having fixedthereon, spaced sprockets 55 and 51. All shafts 31, 58, 52 and 55 areparallel. Shaft 37 has sprockets 58 and 59 fixed thereon adjacent theends of roller 46, and from Figure 1, it will be noted that thepreviously-identified sprockets at corresponding ends of shafts 37, 48,52 and 55, are coplanar and are connected by endless chains 60 and GIpassing over the respective sprockets and meshing with the teeththereon. By this construction, all of the aforesaid shafts are connectedfor simultaneous rotation, and all passes of the parallel chains move insynchronism.

As will be noted upon Figures 1 and 7, the left hand bracket 36, asviewed in Figure 1, has a housing 62 fixed thereto, within which ispositioned a coil spring 63 fixed at its inner end to shaft 37, and atits outer end to housing 62. By this connection, as chains 65 and BImove synchronously with the paper during line spacing operations,sprockets 58 and 59 act to rotate roller 44 and shaft 3? and to placespring 53 under continuously increasing tension. This tension issufiicient so that, when one form has been printed and the paper hasbeen released '(as will be subsequently described), spring 93' acts toreversely move the chains into position necessary to initiate themovement into typing position of the next succeeding form.

As clearly shown in Figures 1 and 2, a shaft 64 passes through, andprojects a substantial distance beyond, brackets The shaft 64 is securedagainst axial movement with respect to brackets 5| and at each endcarries sleeves 65 and 66 ad- 'justably secured in position axiallytherealong by means of set screws 59. Each sleeve has fixed jthereto anarm 61 and 68, respectively, forked as at 67a, Figure 2, to receive apart of the typing machine with which our invention is to be used, suchas the shaft of platen P. It is intended, of course, that these arms 67when in the position shown in Figure 2, shall connect the platen P .andcarriage 22, to move axially as a unit.

While to avoid an excessive number of lines, we have shown the papersupply F, Figure 2, as a single sheet, it will be understood that ourspeed feed attachment has its greatest utility when used in connectionwith a plurality of superposed strips or forms such as are employed inmaking out bills, where one original and oneor more copies of each billare desired. Thus, supply F will usually consist in a plurality ofsuperposed strips with aligned hinge joints H and aligned r perforationsadjacent each hinge line; and in ;order to make the desired copies ofeach bill,

carbon paper must be interleaved with the super- .posed forms as theypass around platen P.

For the purpose of providing the required numform or bill has beencompleted, I provide a backing plate in extending transversely acrosschains 60 and BI, and having its ends in sliding, guided 70 contact withtubes 33. Plate 10 has loops 7| secured thereto, through which therespective chains 69 and El pass. Offset spring arms I2 are secured toeach end plate, so shaped and posilightly contact the respective tubes'n from angle bars 33 and hold the plate in sliding contact with'saidjtubes.

A spring arm 13 has both ends shaped as shown at Figures 9'and 10, andis riveted, or otherwise secured at its central portion, to the rearside of plate 79. A pin 74 is secured to each end of arm 13 adapted,when in the normal position shown at Figure 9', to pass through a holein the corresponding loop "ll and the adjacent link of the chain 69;Means for releasing pins 14 from the chain are shown at 15, in the formof oifset lugs attached to, or integral with the ends of arm 73, andprojecting'forwardly over the top edge of plate 10. When it is desiredto adjust the position of plate 75, relatively to chains 69 and 5|,

the operator simply presses 0n lugs '15 to retract pins 14 to theposition shown at Figure 10, where upon the plate?!) may be manuallyadjusted upwardly or downwardly as desired.

Guide pins 16 are secured to project from each end of plate 19 and areso spaced as to receive the apertured ends of strips 11 which strips areattached, in any desired manner, to the upper edges of respective sheetsof carbon paper C. In this manner, plate 70 and carbon sheets C, may, atthe p'ropertime, be moved upwardly as a unit by the action of spring 53,shaft 37, and chains 65 and BI. Pins 75 are grooved at their outer orfree ends, to receive the forked ends of a guard strip 78, extendingtherebetween.

It is desirable to maintain the corresponding forms or the superposedpaper webs in longitudinally aligned position asthey pass through themachine, not only so that each line of typing shall have the samerelation or spacing with respect to the top andbottom edges of thecorresponding forms, but also so that the superposed forms may be easilyseparated from the web along their hinge lines in a single operation Tothis end, we pro vide the mechanism shown in detail at Figures 6, 8, 1:1and 12.

A strip 19 extends across the rear parallel faces of angle bars 29 andis held in sliding contact with said faces by spring fingers and BI, se-

cured to strip 19 as by rivets 82, and engaging the opposite faces ofbars 29. strip 19 has up.- standing apertu-red lugs 83 and 84 at itsends and pivot bolts 85 and 36 pivotally connect the respective lugswith corresponding lugs 8'! and 88 secured to an operating bar 89 which,as shown at Figure 1, is sufiiciently long so that its ends projectoutwardly beyond bars 29, whereby bar -89 may be conveniently grasped bythe operator. As shown at Figures 11 and 12, bar 89 may be aright-angled strip. By this mounting, bar 89 may be given a pivotalmovement toward and 29. A rod 95 is secured to strip 79 in a positionoffset to the rear thereof, by angular brackets 9 I, each having one armsecured to strip 79 and its other arm apertured to receive the end ofrod 99. Collars 92 are mounted upon rod and fixed thereto as by setscrews 93 in position abutting the respective facing surfaces ofbrackets 9| whereby the rod is secured against axial movement. The rodis notched or channeled at its central position as at 94, Figure 6,

and a tension spring 95 has one hooked end ento, eachso positioned astolie in the path of a series of preformed superposed apertures in thepaper webs F. The "free ends. of. the standards are slotted to receive asmall roller 91, j-ournaled within the slot, on a pin 93. SeeFigure 11.,Thus, when the paper webs. F are properly aligned and positioned in themachine, standards 96 will :pass therethrough when rotated with-bar '89into the position shown at Figure 11, and the superposed forms arethereby held in. correct relative; position. As the paper is fed; byactuation of platen P, the bar 3.9 together with all parts attachedthereto, move upwardly as a unit in. accordance with the paper-feedingmovement.

At one end, spaced from the side edges or the paper, an arm 99 having ahooked end 99a, is secured. to, and extends downwardly from, bracket 87.A stud I!) is secured to the adjacent angle bar 29 near the lower endthereof and the parts are so related that when the paper-aligning meansis at the lower end of its travel, hooked end 99a engages beneath studI90 when bar 89 is thrust rearwardly to move the parts to the positionshown at Figure 12. This construction affords a means whereby thealigning means may be correctly located in position prior to the startof a form-typing operation. If desired, a U-shaped strip It]! may beattached to pivot with bracket 81 and bar 89 and so positioned that oneleg acts as a stop against bar 29 limiting the inward position underurge of spring 95, while the other leg acts to limit outward movement asby engagement against bar 29. In order to assure that the paper does notmove outwardly when bar 89 is thrust outwardly, that is, to assure thatstandards 96 and their rollers are always withdrawn from the aperturesin the paper, a rod N12 is mounted parallel to, and spaced slightlyfrom, strip 19. This mounting may be effected by means of brackets IE3secured to strip 19. Stri or plate 19 is in contact with chains 60 andBI and is secured thereto by bolts l 04, Figure 8, whereby thepaper-aligning means is moved as a unit with said chains. Ahar I05extends between and rigidly joins the upper ends of rods 35.

In Figures 13 to 16, inclusive, We have shown the various significant.steps involved in the use of our speed feed attachment; and forsimplicity we have shown but two paper webs, with a single sheet ofcarbon paper C therebetween. It will be understood, however, that anynumber of webs and interleaved carbon sheets may be used within thephysical limitations of this type of manifolding, and the typing machineitself. Figure 13 shows the webs and interleaved paper in typingposition over platen P. Pins 14 are in engagement with their respectivechains 60 and Bi and standards 96 are engaged within the superposedholes in the paper strips. Therefore, as platen P is operated inline-spacing operations, the paper, chains and standards, move as aunit. As soon as the typing of a form has been completed, the platen isreversely rotated until the carbon sheet is freed therefrom, asindicated at Figure 14, Because of the tension in spring 63, the partsof our attachment are automaticall reversely operated during thismovement. The operator next presses outwardly upon bar 89 to therebymove the parts to the position shown in Figure 12 wherein the paper isfree from the chains 60 and BI. It will be noted that the hook 99a atthis time engages with the stud I90. Thereafter, the paper is fedforward a predetermined amount by rotation of the platen thus bringingthe file holes in the paper out of register with the standards 96. .Atthis time the operator of the machine may rechine on base l9.

lease the pressure on thebar 89. and the standards 9,6 will merely rideon the surface of the paper. The entire assembl including the standardsis retained in position by the engagement of the. hook 99a with the studI00.

It will be apparent that this also holds. the chains stationary andtherethrough supports the carbon sheets in a stationary position.Accordingly, the operator merely rotates the laten until the form is fedout to the first typing line on. the form immediately following the onewhich has just been typed.

During this last mentioned movement of the forms, the file holes of thesucceeding form will move into alignment with the standards 96 whereuponthe spring 95 will move the said standards into the file holes, releasethe hook 99a of the stud mo and once again interconnect the chains andpaper for simultaneous movement. The carbon is thus automaticallyaligned with the next form by a very simple operation.

When the bar 89 and its attached parts have been moved downwardly intoposition such that hook 99a is engaged under stud Hill, the carbon sheetC has been moved to proper position for the start of a new operation, asshown at Figure 15. The platen is then operated to advance thejust-typed form into predetermined position which may be indicated byany suitable gauge or mark on the machine itself. This position is suchthat a set of apertures in the superposed webs are positioned to beengaged by standards 96. The operator then releases bar 89. so thatspring 95 may act to move the standr ards through said apertures andthus positively connect the aligning means and chains to the webs. Thewebs and carbon sheet are then advanced to a position as shown at Figure16 ready to start the typing of a new form. The justtyped form is tornoff as indicated at T, Figure 16, and typing is resumed. The entireoperation just described is completed in a smooth, continuous and rapidmotion requiring only a few seconds at most. Not only does it save largeamounts of time over the operations wherein the carbon sheets areinterleaved by hand, it also effects a large saving in carbon papersince each sheet may be repeatedly used. Furthermore, by pressing onrelease elements 15, to withdraw pins H from the chains 60 and 6|, theoperator may shift the carbon sheets slightly up or down to engage saidpins with the next succeeding links of the chains whereby to bring freshunused portions of the carbon sheets into position such that they willbe used in the succeeding typing operations. In this way substantiallythe entire surface of each carbon sheet is used. New carbon sheets areeasily inserted simply by snapping the forked ends of strip 18 out ofthe grooves in pins IE, removing strips Ti and the attached sheets fromsaid pins, applying fresh sheets in an obvious manner, and snappingstrip 18 back into position.

As shown, our attachment is easily adapted to a machine simply byresting a part of the ma- Screws [5 are loosened and posts l8 adjustedto a height such that the forked ends of arms 6'! may slip over the hubsof the platen knobs. The set screws fixin arms 6! to shaft 64 areloosened and each arm is adjusted to fit snugly against the insidesurface of the adjacent platen knob. These operations require but a fewseconds at most so that our attachment may be connected and disconnectedrapidly from a standard machine whereby a single ma- "chine maybetransferred, almost instaneously, :from standard typing work,-to billingoperations, and vice versa, to thereby save large sums of money whereseparate expensive billing machines had to be purchased. The attachmentis relatively simple, and easy to' attach It requires inc special skillto operate, and an operator can 'learn to use it quickly and easily. I

' In Figure 1'7 the typing machine and manifolding attachment areillustrated with the manifold- ;ing attachment pivoted about the pivots2'! until "it is disengaged from the platen P. The manifoldingattachment may rest on the table which :supports the machine or may abutthe upper track. i3. In either case the typewriting machine .M is freeto be used as a standard machine without any interference from the speedfeed attachment. The attachment may be again placed in :operativeassociation with the platen P bypivot- .ing it about the pivots 2'! andengaging the arms i6! with the shaft of the platen P at either endthereof.

' While, in order to comply with the patent statutes, we have shown anddescribed a specific Zembodiment of our invention, numerous alterations,modifications, and substitutions of equivai-lent parts, will be obviousto those skilled in this art.
